IN COLD BLOOD has
IN COLD BLOOD has a similar plot line, but I don't think that it's a good one, because it's too slow for my tastes. I think it is a great, gritty film, and if you like the old school grindhouse style, you will enjoy it.
IN COLD BLOOD has some very good moments, but if you're looking for a good horror flick in general and want something to look forward to, this is not your movie.
